Specification of Application vfiled June 3,

To @ZZ who/.fi t may Come/"n:

Be it known that l, HARM HENDRIK VAN Snaren, administrator, a subject of the Queen of the Netherlands, and residing at leli't, el ll/laerten rlrompstraat, Netherlands, have invented certain new and useful lfmprovenients in Means Employed in Gard- Accounting Systems, of which the following is a specification.

ln order to ascertain the exact cost of the various articles produced it has been usual in various factories, for the workman to note on a card, containing sundry dates concerning the piece of work, the time .at which he began and ended his tasks. rl`his statement made it possiole for the bookkeepingdepnrtment to calculate the amount the sundry jobs had cost and to fix the total costprice.

This calculation takes up much time as a consequence of the many operations it involves and is further very exacting in view of the accuracy with which it has to be per- Lformed.

In order to simplify this work it has already been suggested to use cards with records of time at the front and corresponding records of wages at the back (or to have the records of wages printed on a separate card), in such a way that, when the job card is punched at two different times7 above or together with the card bearing the record of wages, the perforations in the wage card enable the amount of the wages earned between said periods to be readily calculated.

Now, the object of the present invention is to simplify this operation and make it more concise, by arranging the printed wage-records on a separate card in such a way, that it corresponds to a reversed arrangement of the record on the job-card. It is thus possible to ascertain the amount of the wages by simply laying the job-card, on which the periods at which the work has been begun and ended are punched, upside down on the card with the key-card with the wage-record and to perform an easy subtraction on the back of the jobcard, the result of said subtraction giving the amount of the wages. An advantage of this method of working is further that the card with the wage-record, which is not punched along with the job-card, can always be used as a key.

Letters Patent.

Patented Apr. 13, 192).

raie. serial No. 301,518.

y 53 shows what is to be seen of the key a the wage-card has been placed on upside-down.

rthe working hours run on the wage-card from 6 m. to l0 p. m. in compiling the vage-record one has allowed for an interval between 8g; and 9 a. in. and from l2 to p. mwh `s one has reckoned an extra pay of 25% for overwork between 6 and 8 p. m. and 507'@ for evening work between 8 and l() p. m.

The amounts on the key-record run from the bottom to the top so that the higher figures are at the top, which makes the subtraction easier.

Work l as lasted from 6.20 a. m. till 8.40 p. m. the pay for same amounts according to the key to .61l-el8:3.l6.

That l claim and desire to secure by Letters Patent is:

l. ll-eans employed in card accounting systems for calculating the wages earned by a workman between two given hours, conisting of a wage-card having 'the hours printed in lines across the face thereof, and a key-card having the amounts correspond ing to such hours printed across the face thereof but in the opposite direction to that of said hours so that, when the cards are placed face-toface, the wage ligures corresponding to the hours of commencing and ripping work are disclosed through punch holes in the wage-card at such hours.

2. Means employed in card accounting systems for calculating the wages earned by a workman between two given hours7 consisting of a wage-card having the hours printed in lines across the face thereof and having a blank back7 and a key-card having the amounts corresponding to such hours printed across the face thereof but in the opposite direction to that of said hours so that when the cards are superposed-faceto-face with the blank back of the wagecard iippermost,-tl1e wage gures corresponding to the hours of commencing and stopping work are disclosed through punch holes in the wage-card at such hours.

.3. Means employed in card accounting systems for calculating the wages earned by a workman between two given hours, consisting of a wage-card having the hours printed in lines across the face thereof, and a permanent key-card having the amounts corresponding to such hours printed across the face thereof but in the opposite direction to that of said hours, but having no other markings or punch holes so that when the cards are placed face-to-face, the Wage figures corresponding to the hours of commencing and stopping work are disclosed through punch holes in the wage-card at such hours.

4.. Means employed in card accounting systems for calculating the wages earned by a workman between two given hours consisting of a wage-card having the hours printed in lines horizontally across the face thereof and having the reverse side blank to receive jottings of the wages due, and a. permanent key-card having the amounts corresponding to such hours printed horizontally across the face thereof but in the opposite direction to that of said hours and having no other markings or punch holes, so that when the two cards are laced faceto-face with the blank back o the wager card uppermost, the wage figures corresponding to the hours of commencing and stopping work are disclosed through two holes punched at the appropriate hours on the wage card.

In testimony whereof I alii); my signature.
